Veins carry blood B. TOWARDS the heart. 
The blood is from the body.

Arteries are blood vessels that carry the blood from the heart towards the body.

Veins are major blood vessels that carry blood towards the heart. The pulmonary veins carry blood from the lungs to the left side of the heart. The superior and inferior vena cavae are large vessels that carry oxygen-poor blood from the body to the heart.

Roughly how many more atp’s can be produced via the complete aerobic oxidation of glucose compared to that produced by glycolysi
Lubov Fominskaja [6]

Roughly 15 times more ATP can be produced via the complete aerobic oxidation of glucose compared to that produced by glycolysis alone.

<h3>What is Glycolysis?</h3>
  • The metabolic process known as glycolysis turns the sugar glucose (C6H12O6) into pyruvate (CH3COCO2H). The high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process (NADH).
  • A series of ten enzyme-catalyzed processes make up glycolysis. the binding energy of carbs is captured. One metabolic route that doesn't require oxygen is glycolysis (In anaerobic conditions pyruvate is converted to lactic acid).
  • Glycolysis occurs frequently in various species, which suggests that it is an old metabolic route.
  • In fact, the events that makeup glycolysis and its companion process, the pentose phosphate pathway, take place in the oxygen-free environment of the Archean oceans, likewise in the absence of enzymes, and are catalyzed by metal.

Explanation:

changed genes is passed on to the next generation. Most mutations are bad, but some of them make the organism more successful in its life. Organisms that inherit that favorable new gene are likely to become more abundant than others of the species. (geologic times)

Which of the following statements describe how technology and research changed the understanding of genetics? Select all that ap
andrey2020 [161]

Answer:

  • Past genetic knowledge has mostly been replaced.
  • Early researchers were hampered by a lack of knowledge of DNA structure and function.

Explanation:

Genetics is the part of biology that studies heredity, that is, how traits are passed down from generation to generation. Many technologies have been created so that scientific research can find new genetic discoveries and facilitate our understanding on this subject.

The first scientific research that tried to explain genetic phenomena was created long ago, but this research generated an archaic knowledge that can be replaced thanks to technology and scientific advancement in this area. This archaic knowledge is the result of research where researchers were unaware of the existence of the DNA molecule, which is the main vehicle in the transmission of heredity.

Unbeknownst to DNA, these researchers attributed heredity to elements that do not correspond with what actually happens, but we cannot dismiss the importance of such research for the technologies and genetic knowledge we have today.
